JOHN G. SHODBON, OF MILWAUKEE, WISCONSIN, ASSIGNOR TO JAMES MANUFACTURING COMPANY, OF FORT ATKINSON, WISCONSIN, A CORPORATION OF WISCONSIN- BABN-VENTILATOR.

Specification of Letters I'atent.

Application filed September 13, 1918. Serial No. 789,646.

To all whom it may concern:

Be it known that I, JOHN G. SHODRON, a citizen of the United States, residing at Milwaukee, county of Milwaukee, and State of Wisconsin, have invented new and useful Improvements in Barn-Ventilators, of which the ,following is a specification.

My invention relates to improvements in barn ventilators and it pertains to that class which are adapted to be used with barns having a lower compartment for cattle and other stock and an upper compartment for storing hay, grain and other feed. One of the primary objects of my invention is to provlde more efficient means for properly ventilating each of said compartments independently of the other. In other words I provide a stationarycupola having outwardly and downwardly inclined slats or louvers between which air is free to escape from the upper compartment and a revoluble wind controlled ventilator supported from such cupola and connected through air duets with the stables or lower compartments of the barn through which ducts such compartments are ventilated.

vMy invention is further explained by reference to the accompanying drawings 1n which- Figure 1 represents a vertical section of the barn provided with my improved ventilating system.

Fig. 2 is ayertical section of that part of the ventilator located above the roof of the barn- Fig. 3 is a detailed view showing a vertical section of a portion of the revoluble ventilator and a device for supporting the same.

Fig. 4 is also a detailed view part in sec tion showing a device for detachably connecting a revoluble sleeve with the stationary part of the ventilator.

Fig. 5 is a horizontal section drawn on line a:-:v of Fig. 2.

- Like parts are identified bythe same reference numerals throughout the several views. 1 represents the lower compartments of the barn which is used for stabling cattle and other stock. 2 is the upper compartment used for storing hay, grain, etc. 3 is a on 01a of ordinary construction which is rigi y aflixed to the roof 4 of the barn and is provided with a plurality of slats or louvers 5 between which the air is free topass from the upper compartment 2 to the exterior. It is a well known fact that the motive power for maintaining a continuous current of air from the interior to the exterior of a barn is produced by the differ ence in temperature between the air in the interior and exterior. The air on the inside of the barn being warmer than that on the outside rises and passes out between the slats or louvers 5. TlllS movement is also assisted by the suction of the wind blowing across the top of the out take ducts, substantially as a chimney has a stronger draft when the wind is blowing hard than when the air is at rest.

What has been stated as to the action of the air escaping from the upper compartment 2 is also true as to the action of the air passing from the lower compartment 1. The air in the lower compartment is raised to a higher temperature by the presence of the stock therein when it passes up through one or more ducts 6 to the central duct 7 when it passes from thence into the revoluble dome 8. and from thence into the exterior air through the outlet opening 9. The dome 8 is revolublysupported from the upper end of the shaft 26 and said dome is adapted to revolve by the action of the wind the same being operated by the vane 11 and shaft 12.

The dome 8 is provided with a tapered chamber 13 which converges from the inlet end 14 to the outlet end 15. The lar er inlet end 14 is retained toward the win b the action of the vane 11 operating throng the shaft 12. It will be obvious that as wind passes through the chamber 13 its velocity is The air thus escaping from the chamber 13 at a high velocity has a tendency to create a strong suction which exerts a powerful pull on the air in the ducts 6 and 7 which communicate from the lower chamber 1 to the revoluble dome 8. The inlet end ofthe. tapered chamber 13 is rovided with a screen 16 which prevents birds dust and other refuse matters from enterlng such 0 ber, while the dome at the opposite end of said chamber is provided with a screen 17 which also serves to exclude birds, dust and other refuse matter from the dome 8. 18 is a storm band which is rigidly supported from the duct 7 by a plurality of brackets 19. The brackets 19 are secured at one end to the storm band by rivets 20 and at their other ends to the duct 7 by a plurality of rivets 21. 22 and 23 are annular flanges or so-called skirts which are respectively connected at their upper ends to the duct 7 by a plurality of rivets in the ordinary manner. The annular flanges or skirts 22 and 23 diverge downwardly and outwardly and they together with the band 18 coiiperate to protect the ventilator from injurious effect of the elements while the skirts aid in acceleratlng the circulation or escape of the air from the barn. The duct 7 together with the ventilator connected therewith are supported from the top of the cupola 3 by the inclosing walls 24, which walls are preferably formed of heavy galvanized sheet metal. The revolving dome 8 is supported from the duct 7 through the radial arms 25, vertical spindle 26 and a plurality ofinclined rods 27. The arms 25 aresupported at their outer ends from the ducts 7 and are connected therewith through rivets or in any convenient manner. The spindle 26 is connected near its center with the sleeve 28, while the upper ends of the rods 27 are connected with said sleeve 28 through the lugs 29 and bolts 30. The revoluble dome 8 is provided with a hollow central shaft 31 which shaft is rigidly connected at its lower end with the walls of said dome through the bracket 32 and a plurality of bolts 33, whereby said revoluble dome and central shaft 31 are adapted to revolve together. The upper end of the hollow shaft 31 is connected with the'apex of the dome 8 through the central member 34. The member 34 is provided with a conical seat 35 for the reception of the tapered upper end of the stationary spindle 26. The

stationary spindle 26 is rigidly affixed near its center to the sleeve 28, whereby it is obvious that said dome is free to turn on said supporting spindle with a minimum resistance, and whereby the mouth or larger open end of the chamber 13 is always retained in the direction of the wind and whereby a strong upward current of air is induced shown in Fig.4 the inwardly projectinglug 38 is free to pass the bead 39 until it is brought in contact with the bead 40. When this is done the hollow shaft 31 is turned a half revolution, whereby the inward projecting lug 38 will be brought inalinement with a groove 41 in said bead 40 when the hollow shaft 31 together with the-dome 8 is free to projecting lug 38 is free to pass the grooveformed in the flange 39 whereby the dome 8 is brought to its normal position for use.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

1. The combination with a barn having a plurality of compartments, of a stationary ventilator connected with one of said barn compartments, a wind actuated revoluble aspirating ventilator, and a ventilating duct leading thereto from one of the other barn compartments through the stationary ventilator.
